31 some general techniques on how to debug kernel with gdb.
35 If you are debugging Microdroid kernel that you have built [locally](
36 ../../build/microdroid/kernel/README.md), then look for `out/dist/vmlinux` in your
37 kernel repository.
39 If you are debugging Microdroid kernel bundled with the `com.android.virt` APEX,
40 then you need to obtain the build ID of this kernel. You can do this by

82 You also need the image of the kernel binary with debuggin enabled. The kernel
83 binary should be the same as the actual kernel that you used in the Microdroid
84 VM that crashed. To identify which kernel it was, look for the kernel version
94 of the kernel.
